Before you go: the shape and the flights
Three decisions shape this trip more than any single sight. Get them right and the route below runs like clockwork.
Three regions, not four
In ten days, three regions fit and four don't: ~3 nights Bangkok, 3 Chiang Mai, 4 on one island. Each needs three nights to be more than a stopover. Fly into Bangkok and out of your island's airport (open-jaw), and keep a buffer for connections.
Fly the internal legs
Bangkok → Chiang Mai is a 70-minute flight (cheap, frequent); Chiang Mai → the islands is a flight too (no practical train or road). The overnight sleeper train (~13h) is a lovely experience but a full day — save it for 14+ day trips.
Pick the island by the season
The two coasts run opposite monsoons: the Andaman (Krabi, Phuket, Phi Phi) is best Nov–Apr; the Gulf (Samui, Phangan) best Feb–Sep. Match the coast to your dates — and don't mix an Andaman and a Gulf island (no direct ferry).
Days 1–3 · Bangkok
Bangkok: golden temples, canals and street food
Start in Bangkok — a hot, loud, exhilarating megacity of gilded temples, canal life, street food and rooftop bars. It's overwhelming and wonderful in equal measure, and it's the country's transport hub, so give it three days to orient yourself and dive in.
Getting there
Fly into Bangkok (Suvarnabhumi, BKK, or Don Mueang, DMK); the Airport Rail Link or a metered taxi reaches the centre. Beat the traffic with the BTS Skytrain and MRT metro (cheap and cool), the Chao Phraya river boats, and Grab. Bangkok is the hub for the 70-minute flight north to Chiang Mai.
The Grand Palace & the great temples
The dazzling Grand Palace and Wat Phra Kaew (the Emerald Buddha), Wat Pho with its enormous Reclining Buddha (and a temple-massage school), and Wat Arun rising across the river. The golden, spiritual heart of the city — dress modestly, with shoulders and knees covered.
The river, the markets & the street food
A Chao Phraya river boat and the old canal (khlong) neighbourhoods, the vast Chatuchak weekend market, and the street food of Chinatown (Yaowarat) after dark — Bangkok is one of the world's great eating cities, and much of the best of it costs a dollar.
Rooftops, malls & the buzz
A sky bar for the skyline at dusk, the air-conditioned mega-malls, and the late-night energy of Khao San Road or Sukhumvit. For a full day-by-day plan of the city, follow the dedicated Bangkok itinerary and the free-things guide, then rejoin this route for the flight north.
Dress modestly for the temples, and ignore any friendly stranger who says a temple is 'closed today' and offers a tuk-tuk to a gem shop — it's the city's classic scam. Use the BTS/MRT and river boats rather than taxis at rush hour, and book your Chiang Mai flight ahead.
Days 4–6 · Chiang Mai
Chiang Mai: temples, mountains and slow days
Fly 70 minutes north to Chiang Mai — the laid-back capital of the north, a moated old city of some 300 temples ringed by jungle mountains, famous for its food, its crafts and its gentler pace. Three days cover the temples, an elephant day and a cooking class.
Getting there
A domestic flight (BKK → CNX) takes about 70 minutes and is cheap and frequent (Thai, AirAsia, Nok). Fly early to keep the day. The much-loved overnight sleeper train is a wonderful experience but costs you a day — save it for a longer trip. Chiang Mai's Old City is walkable; use songthaews (shared trucks) and Grab for the rest.
The Old City temples & Doi Suthep
The moated old town's temples — the golden Wat Phra Singh and the ruined, elephant-buttressed Wat Chedi Luang — and, on the mountain above the city, Wat Phra That Doi Suthep (best at sunrise) for the glittering chedi and the view over the valley.
An ethical elephant sanctuary & a cooking class
Two of Chiang Mai's signature days: a full day at a genuine, ethical elephant sanctuary (feeding and bathing, no riding), and a hands-on Thai cooking class in the countryside — from the market to a dozen dishes. Both book out, so reserve ahead.
Markets, Nimman & the mountains
The Sunday Walking Street and the Night Bazaar for handicrafts and food, the café-and-design district of Nimman, and a day trip up Doi Inthanon (Thailand's highest peak) or to the hippie mountain town of Pai. The relaxed counterweight to Bangkok.
Choose an elephant sanctuary that does not offer riding — the ethical camps let you feed and bathe the elephants only. Crucially, avoid Chiang Mai in the March–April 'burning season,' when agricultural haze fouls the air (see our best-time-to-visit-Thailand guide). In November, the Yi Peng festival fills the sky with lanterns.
Days 7–10 · the islands
The islands: the beach finale
Fly south for the finale — limestone cliffs and turquoise water on the Andaman coast, or the palm-fringed Gulf. Four nights to island-hop, snorkel, eat fresh seafood, and finally stop looking at your phone. Which island you choose depends, above all, on your travel dates.
Getting there
Fly from Chiang Mai (direct where available, or via Bangkok) to your island's airport: Krabi (KBV) for Railay and Ao Nang, Phuket (HKT) for the most flights and the Phi Phi ferries, or Koh Samui (USM) on the Gulf — its own airport makes it the easiest connection. There's no sensible rail or road option from the north; flying is the way.
Choose your coast by the season
Thailand's two coasts run opposite monsoons. The Andaman side — Krabi, Phuket, Phi Phi, Koh Lanta — is best November–April, with the iconic karst cliffs and clearest water. The Gulf side — Koh Samui, Koh Phangan, Koh Tao — is best roughly February–September (and wettest in November). Match the coast to your dates.
Island-hopping & the beaches
From Krabi's Ao Nang, a four- or seven-island longtail tour (Railay, Chicken Island, the Hong Islands) is the classic day out; from Phuket, the ferry to Phi Phi and Maya Bay; from Samui, boats to the Full Moon beaches of Koh Phangan and the diving of Koh Tao. Snorkelling gear and lunch usually come included.
Slow right down
The whole point of the last four nights: a beach, a Thai massage (some of the best-value wellness on earth), grilled seafood at a shack on the sand, and an unhurried sunset. After six days of cities and temples, you've earned a plan that's just 'the beach.'
Never combine an Andaman island and a Gulf island in one 10-day trip — there's no direct ferry between the coasts, and the fly-via-Bangkok transfer burns most of a day (travellers routinely lose 13 hours on a mis-sold 'two-beach' Phuket–Samui transfer). Pick one coast, island-hop within it, and build a buffer for the ferry-to-flight connection on your last day.
Getting between the regions
Internal flights are the spine of this trip. Here are the legs, the 2026 options, and how the islands connect.
| Leg | Options (2026) |
|---|---|
| Bangkok → Chiang Mai | Flight ~70 min (BKK/DMK → CNX), cheap & frequent (Thai/AirAsia/Nok). Or overnight sleeper train (Train 13, ~13h, ~$40 2nd-class sleeper) — a day, save for 14+ day trips. |
| Chiang Mai → the islands | Fly — CNX → Krabi (KBV) / Phuket (HKT) direct where available, or via Bangkok (~+3h). To Koh Samui (USM): Bangkok Airways, usually via Bangkok. No practical train/road. |
| Island-hopping (same coast) | Andaman: Phuket → Phi Phi ferry ~2h; Ao Nang → Railay longtail ~15 min + island tours. Gulf: Samui → Phangan/Tao ferry. Quick and scenic. |
| Between the coasts | NO direct ferry Andaman ↔ Gulf — you must fly via Bangkok (most of a day). Don't mix an Andaman and a Gulf island on a 10-day trip. |
| Order & airports | Fly into Bangkok (BKK/DMK), out of your island (HKT / KBV / USM — some international). Open-jaw avoids backtracking. |
| City transport | Bangkok: BTS/MRT + river boats + Grab. Chiang Mai: walkable Old City, songthaews & Grab. Islands: scooter, songthaew, longtail boats. |
The other quiet upgrade is context. A Bangkok temple or a Chiang Mai ritual you understand is one you remember — so before Wat Pho or Doi Suthep, it helps to have the story in your ears rather than reading a sign in the heat.
Plan it with HipiMind
Plan this trip by talking
A three-region trip with internal flights and a season-dependent island choice is exactly where a planner earns its keep. That is what HipiMind is built for. It is a voice-first AI travel assistant: describe your trip out loud — “ten days in Thailand, Bangkok, Chiang Mai and a beach, travelling in December” — and it turns the conversation into a day-by-day itinerary with every stop and flight leg placed on a map. Because it maps the whole route, you can see how the three regions split, which coast and island suit your dates, why to fly rather than take the train, and where the buffer days go — and fix the plan before you book.
For each place, ask HipiMind to generate a long-form audio guide — the temples of Bangkok, the Lanna kingdom of the north, the geology of the karst coast — and listen hands-free as you go. It is interruptible: pause to ask a question, get an answer, and resume where you left off. It plans and narrates in the language you speak, across 32 languages, right in the browser — no app to install.
The free tier includes 3 voice sessions and 1 audio guide per calendar month. HipiMind Plus is $7.99/month ($59/year) with 60 voice sessions, 20 audio guides, and full trip memory across journeys. HipiMind plans and narrates — it does not book flights, ferries, hotels, or tours, and it is not a GPS-triggered on-site tour; confirm times, fares, and reservations with the provider.
Thailand itinerary FAQ
How many days do I need for Thailand — Bangkok, Chiang Mai and the islands?
About ten days is the sweet spot for this three-region trip: roughly three nights in Bangkok, three in Chiang Mai and four on a southern island, plus a buffer for connections. Each place genuinely needs three nights — two is a stopover, three is when you stop rushing and actually enjoy it. The islands especially reward the longer stay. With two weeks you could add the overnight train, a second island on the same coast, or a slower pace; with only a week, drop one region rather than trying to cram all three.
What's the best order for a Bangkok–Chiang Mai–islands trip?
Bangkok → Chiang Mai → a southern island is the natural order: arrive in the capital and orient yourself, fly north for the temples, mountains and slower pace of Chiang Mai, then finish on the beach — the perfect wind-down after six busy days. Fly into Bangkok (Suvarnabhumi or Don Mueang) and out of your island's airport (Phuket, Krabi or Samui) on an 'open-jaw' ticket so you never backtrack. Reversing it (beach first) works too, but ending on the sand is the classic, and the more relaxing, choice.
Should I fly or take the train between Bangkok and Chiang Mai?
Fly for a ten-day trip. The Bangkok–Chiang Mai flight takes about 70 minutes and is cheap and frequent (Thai, AirAsia, Nok, Bangkok Airways). The overnight sleeper train (Train 13, about 13 hours, roughly $40 for a second-class sleeper berth) is one of the great Thai experiences — countryside at dusk, mist in the hills at dawn — but it costs you a full day, which is a lot on a short trip. Save the train for itineraries of two weeks or more. From Chiang Mai to the islands there's no practical train or road option, so fly.
Which Thai island should I choose?
Choose by the season first, then the vibe. Thailand's coasts run opposite monsoons: the Andaman coast (Krabi, Phuket, Phi Phi, Koh Lanta) is best November–April, and the Gulf coast (Koh Samui, Koh Phangan, Koh Tao) is best roughly February–September (and wettest in November). Within that: Krabi has the most spectacular scenery (the Railay cliffs); Phuket is the biggest and has the most flights and day-trip options; and Koh Samui is the easiest to reach (it has its own airport, with near-direct hops from Chiang Mai). See our best-time-to-visit-Thailand guide for the full coast-by-coast timing.
Can I visit two islands or both coasts?
Not comfortably in ten days — and never one island on each coast. There is no direct ferry between the Andaman and the Gulf, so a Phuket-to-Samui-type transfer means flying via Bangkok and losing most of a day (people regularly report 13-hour misrouted transfers). If you want two islands, stay on one coast and hop by ferry — for example Phuket to Phi Phi to Krabi on the Andaman side — which is quick and scenic. To properly do both coasts, you need two weeks, and even then you'll spend a travel day crossing between them.
When is the best time to do this trip?
November to February is the ideal window: Bangkok and Chiang Mai are in their cool, dry season, and the islands are at their most reliable (the Andaman coast especially). Avoid Chiang Mai in the March–April 'burning season,' when farm-clearing haze harms the air quality, and note that Songkran (the mid-April water festival) is huge fun but very hot and crowded. The green season (roughly June–October) brings brief afternoon downpours, lower prices, and a shift in which island coast is driest — so if you travel then, match your island to the season. Our best-time-to-visit-Thailand guide has the month-by-month detail.
How can HipiMind help me plan a Thailand trip?
A three-region trip with internal flights and a season-dependent island choice is exactly where an AI planner earns its keep.
